Extremely slow battery charging on Nexus 5 after updating to lollipop

[Antony Sahayaraj]

Hi Ken,
Even I faced the same problem. All you need to do is clear the cache. Go to settings>storage>cached Data. After that restart your phone. Now try charging, it should work fine.

Hi all,

Same is happening for me. I have always only used two chargers:
1. At night a USB plugged into wall
2. At Work a wireless charger.

Since the update I have only been able to charge the phone with the wireless charger as normal. The USB charges very very slow as people above have mentioned.

Same problem here, 61% and is a new nexus 5 32gb, updated OTA, im getting frustrated-angry

 

[joakin2k]

Help !, same here, 60% updated OTA in a new nexus 5....

 

[aaa4191]

i am feeling sad bcoz of my n5...updated OTA 2 days ago and overnight charging gave me 66% lat night...help.
:'(

I absolutely agree, my LG Nexus 5 now crawls while recharging, it took 5 hours yesterday, never happened before

I encountered the same problem and after some online research tried the following and the problem got resolved.

All you have to do is clear cache data.

1. Go to Settings -> Storage -> Cached Data
2. cellphoneforums(dot)net/lg/t366718-lg-nexus-5-master-reset-clear-cache-partition-boot-safe-mode.html#axzz3IF3b5equ
(replace (dot) with actual 'dot')

Follow instructions for “Cache Partition Management”
3. Reboot your phone

Hope this works for you!!!

Cheers

The situation regarding charging is very simple. Firstly unless pins 2&3 of the USB connector are shorted together the Nexus 5 assumes it's plugged into a USB Data port and as per Android O/S will only ever draw 500mA of current. No In-Car chargers short together pins 2&3 so they will never "fast" charge regardless of what current they specify. The AC Charger that comes with the phone has pins 2&3 shorted together and will happily supply up to 2 Amps at an output of around 4.9 Volts.
Also most In-Car chargers are pretty rubbish. They all use a similar switched mode power supply chip which they say will deliver 2.1 Amps, they won't! I have tested a number of chargers, they will remain at 4.9-5 Volts at a current drain of up to 500mA, above that the output voltage drops, at 2.1 Amps the voltage has dropped to around 3.9 Volts, a drop of 20% absolute rubbish.

I'm having the same slow-charge problems as other users here, regardless of whether I use the Nexus 5 supplied charger, computer USB2 port, or car charger. This glitch began the instant I upgraded to Lollipop and had never occurred prior to the update. It seems extremely likely that this is a lollipop glitch, not a USB or hardware issue. I hope android issues an update soon.

 

[Charles Turner5]

The problem has nothing to do with the software, just the crap chargers, if you apply 5 Volts to the phone capable of delivering >2-3 Amps then it will charge as quickly as possible.

 

[Sortedtales]

Why would the same Google-supplied OEM charger suddenly perform differently after an OS update?

 

[Charles Turner5]

This is so simple, the charger is not capable of supplying the necessary current at 5 Volts. Lollipop may well in its quiescent state consume more power than its predecessor, the crap chargers cannot supply the required current at whilst maintaining 5 Volts simple.

 

[Sortedtales]

It's the battery that requires current, and the battery is the same. The OS in its 'quiescent' state draws almost no current. If lollipop was so power hungry in its quiescent state then it could be expected that it would drain power faster than the previous OS, but it doesn't, it uses power more conservatively, or at least that is what google claims, and indeed that's my experience as well. Previously my google supplied crap charger could charge my phone 2 hrs while using mapping apps on my phone. Also your crap-charger theory also doesn't explain why the charging process stalls-out at around 60%.

 

[Charles Turner5]

Brian, you really haven't a clue. Simply connect your AC charger with the phone switched on and measure the voltage, it will be significantly less than 5 Volts. Now connect a proper 5 Volt stabilised supply capable of a maximum current of say 5 amps, the voltage will remain at exactly 5 V and the phone (battery) will fully charge quickly.

Well,

In my humble opinion, and completly based in common sense and experience of the last days, the problem may be with the hardware.
What I think it's causing these problems is a battery or other component that was used in the first editions of the Nexus 5 and not in the latest editions.
My Nexus was bought in January, so I believe that is the problem with it. It's just not compatible with the Project Volta, hence the resulting problems.

I'm sending it to warranty today because it simply does not charge as you can see by the battery chart! ...

Notes on the chart:
1 - To get to 100% it had to charge switched off on the wall charger for 25 hours.
2 - On the first day I used the phone "normally" but with some caution.
3 - On the second day I left it on charge in the wall charger but left the wifi on because I forgot ... but it's a strange curve...
4 - Notice the strange battery drain when turned off on the end of the 4/12
5 - What made me decide to send the device to warranty is the charging overnight in the day 5/12... It simply didn't charge a thing!!



Let's see what LG has to say...

Thank you all for the opinions!

Obviously short pins 2&3 together on the USB.

Well, I know that solution may work.
Yesterday I connected it to an universal laptop charger that has a voltage indicator and an output of 5V with 1A. The indicator was stable at 5,3V and it kept discharching.

I've tried to charge it with a Galaxy Tab charger that has 5V and 2A for 20 min. It worked. After 20min it went from a dead battery to 20%, which is pretty nice, however the screen lost color and started to bleed some purple, so I don't want to try it again.

I have a similar problem. Got the lollipop update a few weeks back. Things were ok till day before. My phone battery is charging ridiculously slowly. I kept it on charge (wall socket as usual) the whole night (12hrs) and it was only 84% charged. It takes easily an hour to charge 2%. My colleague had a similar problem and she suggested that I charge in aeroplane mode or switch off all data and wifi and try. It worked. Phone is charging at the same rate it did prior to the udpate. But it is extremely annoying!! Whats the point of having a smart phone if i have to switch off data everytime I want to charge my phone. Google people, please fix this.

Hiperlouro, if pins 2&3 are NOT shorted together the phone will only draw a maximum of 500mA.

What do you mean with shorted together? Can you show a picture?
